inject other objects are normal , they jsoupService always NULL. Very puzzled.
------ Solution ---------------------------------------- ----
@ Resource
private JsoupService jsoupService; like that look .
JsoupService is not the case in this Service tag you have a problem

------ For reference only ---------------------------------- -----
@ Resource (name = "jsoupService") public void setJsoupService (JsoupService jsoupService) { this.jsoupService = jsoupService;}
landlord to test whether this method has been executed
------ For reference only ------------------------- --------------

tested , the output has a value.
------ For reference only -------------------------------------- -
service can not be injected into the service in
------ For reference only ---------------------------- -----------

I changed the @ Service @ Component ("jsoupService") is still not ah.
------ For reference only -------------------------------------- -

other injected into the service did not appear in this situation ah.
------ For reference only -------------------------------------- -
System.out.println (jsoupService)
view this object does not exist . If there is a problem to explain returns , check getsyllabus logic.

------ For reference only ---------------------------------- -----

output of these two places have a value , other places no value on it.

  
  	public JsoupService getJsoupService() {
                  System.out.println(jsoupService);//这里输出有值
  		return jsoupService;
  	}
  
  	@Resource(name ="jsoupService")
  	public void setJsoupService(JsoupService jsoupService) {
                  System.out.println(jsoupService);//这里输出有值
  		this.jsoupService = jsoupService;
  	}
  
  

------ For reference only ---------------------------------- -----
you directly call getJsoupService () method to see whether the correct execution
------ For reference only ----------------- ----------------------

output is a null value.
------ For reference only -------------------------------------- -
@ Resource
public void setJsoupService (JsoupService jsoupService) {this.jsoupService = jsoupService; try this way }
------ For reference only ----------------------------- ----------
check the configuration

------ For reference only ----------------------- ----------------
1, you have to look at the first choice , your every component is not already created, using junit to test it .
2, you put the following code simply rephrase .

@ Resource (name = "jsoupService")
public void setJsoupService (JsoupService jsoupService) {
System.out.println (jsoupService) ;/ / output are here value
this.jsoupService = jsoupService;
}
as:
@ Resource (name = "jsoupService")
private JsoupService jsoupService;
Do not set above plus annotated .
------ For reference only -------------------------------------- -

same. Useless .
------ For reference only -------------------------------------- -

  	<context:annotation-config/>
  	<context:component-scan base-package="cn.recx.wechat"/>
